DHS International Cyber Partner Act of 2023

This bill authorizes the Department of Homeland Security (DHS) to assign personnel to foreign locations to support cybersecurity and infrastructure security missions, directly affecting DHS staff and foreign governments with whom they partner. Key provisions require DHS to obtain the Secretary of State's concurrence for assignments and coordinate with the chief of mission in the host country, ensuring alignment with diplomatic protocols. It also amends CISA's authority to include international partners in cyber planning and allows DHS to enter agreements with foreign governments for critical infrastructure security, with costs recoverable from partner entities. The bill enables DHS to formally expand its international cyber cooperation while maintaining existing diplomatic frameworks.
